Grinding Disc Proma 200x40x16 mm soft (MPN 25250016)

Proma soft grinding disc 200 x 40 x 16 mm is a radial abrasive accessory intended for bench and portable grinders. The disc features a softer contact surface compared with hard grinding wheels, enabling controlled material removal and improved surface finish. It is suitable for smoothing, deburring and light stock removal on metal, welded joints and other workpieces where a less aggressive abrasive action is required. The design fits grinders with matching mounting dimensions and is intended for finishing and preparation tasks rather than heavy-duty cutting.

Advantages

The soft construction reduces vibration transfer and allows conforming to slightly irregular surfaces, producing a more uniform finish. Softer backing material offers better control at lower pressures, minimizing risk of gouging and overheating sensitive parts. The disc balances abrasive effectiveness with a gentler touch for tasks that demand edge blending, chamfer smoothing and final surface preparation.

Suitable for

• Smoothing and blending weld seams on steel and stainless steel
• Deburring edges and removing burrs from machined parts
• Surface preparation before painting or coating
• Light material removal and finishing on castings and fabricated parts

Key specifications

• External diameter: 200 mm
• Face width: 40 mm
• Bore diameter: 16 mm
• Construction: soft-backed grinding disc designed for finishing
• Typical applications: finishing, deburring, surface preparation on metal and similar materials

How to use

Mount the grinding disc on a compatible bench or portable grinder that accepts a 16 mm bore. Ensure the disc is securely fastened and that the grinder’s speed does not exceed the disc’s rated maximum RPM as specified by the grinder manufacturer. Use steady, moderate pressure and maintain a consistent angle to achieve an even finish; avoid forcing the disc into the workpiece. Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection where dust is generated. Inspect the disc before each use for cracks or damage and replace if any defects are found.

Usage recommendations

For best results, use the disc for light grinding and finishing operations rather than heavy stock removal. Combine with appropriate cleaning and deburring procedures and select a suitable grinder speed to match the material and task.
